[0024] The following will provide a clear and complete description of the technical solutions in the present embodiment of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only preferred embodiments of the present invention.

[0025] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present invention belongs. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0027] See attached Figures 1 to 7 In the embodiment of the utility model, a backlight lamp board structure of an advertising machine and an advertising machine include a first circuit board 10 and a second circuit board 20, wherein the second circuit board 20 is connected to the outer edge of the first circuit board 10; the first circuit board 10 is a single-layer circuit board, and the second circuit board 20 is a double-layer circuit board. The first circuit board 10 is installed with a plurality of lamp beads 11, and the second circuit board 20 is installed with an IC driving module 21, wherein the IC driving module 21 controls the connection of the lamp beads 11.

[0028] Specifically, the first circuit board 10 and the second circuit board 20 are both rectangular, the long side of the second circuit board 20 is connected to the short side of the first circuit board 10, and the long side of the second circuit board 20 is smaller than the short side of the first circuit board 10. That is, the present application uses a single-layer circuit board with a larger area (lower cost) to arrange the lamp beads 11, and a double-layer circuit board with a smaller area (higher cost) to arrange the IC driver module 21, and the IC driver module 21 controls and connects the lamp beads 11; thereby saving the manufacturing cost of the backlight source lamp board and reducing the wiring exposed outside the advertising machine.

[0029] Typically, the second circuit board 20 can be connected to the outer edge of the first circuit board 10 by welding. In practical applications, the first circuit board 10 is typically made of an aluminum substrate, and the second circuit board 20 can be made of an aluminum substrate or a fiberglass board; the lamp beads 11 are typically LED lamp beads 11. Preferably, a plurality of the lamp beads 11 are arranged on the first circuit board 10 in a rectangular array.

[0030] The present application also discloses an advertising machine, comprising a chassis 30 and a backlight source disposed in the chassis 30, wherein the front side of the backlight source has a liquid crystal 31; the backlight source is the aforementioned backlight source light board structure of an advertising machine; the rear side of the chassis 30 is provided with a heat dissipation fin plate 32; in actual application, the backlight source light board structure of the advertising machine is formed by splicing a plurality of the aforementioned backlight source light board structures, that is, by splicing (usually welding) the long sides of a plurality of first circuit boards 10; Figure 1 As shown, it is a schematic diagram of the structure of the backlight lamp board of the present application (a first circuit board 10 is spliced ​​with a second circuit board 20), and in Figure 2 and Figure 3 In the figure, it is a schematic diagram of the structure of a plurality of backlight source lamp panels of the present application being spliced ​​and assembled with each other, and the required backlight source size specifications are spliced ​​and assembled according to actual needs.

[0031] It can be supplemented that: in actual application, a control box is installed on the back of the advertising machine, the chassis 30 has a back plate 33, and the heat dissipation fin plate 32 is attached to the back plate 33; the rear side of the advertising machine is usually also installed with a control box 50, the back plate 33 is provided with an avoidance hole, and the control box 50 passes the avoidance hole through the wiring to control the backlight source lamp board (IC driver module 21). In the prior art, in order to save costs, the circuit board on which the LED lamp beads 11 are usually installed is a single-layer circuit board, but the single-layer circuit board cannot be installed with an IC driver module, so the designer usually sets the IC driver module in the control box 5, and then the IC driver module is inserted into the advertising machine through the wiring and electrically connected to the first circuit board 10, so as to achieve the purpose of controlling the LED lamp beads 11; this installation method has a large number of LED lamp beads 11, which leads to a large number of wiring harnesses passing through the avoidance holes, so that a larger size of avoidance holes or a larger number of avoidance holes need to be set, which is very troublesome; at the same time, too many wiring harnesses are exposed to the outside, which not only affects safety, but also is inconvenient for installation and arrangement and unsightly.

[0032] The design focus of the utility model is that it mainly adopts a large-area single-layer circuit board to install LED lamp beads, a small-area double-layer circuit board to install IC driver modules, and splices the single-layer circuit board and the double-layer circuit board, thereby solving the problems of high manufacturing cost and complicated wiring of the backlight board of the existing advertising machine, and its welding process is relatively simple, which is more suitable for the actual production and use of advertising machines and suitable for popularization and application; secondly, the use of an aluminum substrate to make a single-layer circuit board is also beneficial to the heat dissipation advantage of the LED lamp beads.

[0033] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
